Throughput improvement and spectrum allocation in femtocell networks by pricing strategy

In this paper, we propose the method for allocating spectrum resource efficiently for the service provider to get the highest revenue due to limited spectrum resource. The concept of this proposed method is to find optimal sub-channel for femtocell from optimal ratio of macro-femto network that corresponds to the highest revenue point by using pricing strategy. Simulation results show that our proposed method can improve the total throughput of system over the one of the optimal sub-channel with the fixed sub-channel.
